The red light shot out and landed accurately on the man in black in front of him, who was about to walk to the factory, and happened to have his back to Nuan Nuan and Brother Xiaohu, so he didn't know that he was illuminated by the evil spirit detector.

The red light shone on his back, and a purple glow appeared on his back.

The detector in Brother Xiaohu's hand vibrate, and the vibration was so strong that Brother Xiaohu almost didn't hold it.

It has now been determined that the man in black is an evil spirit.

Nuan Nuan flipped the spirit slayer, and the blue light flew silently towards the back of the black-clothed man's head.

After the man in black was shot, he was dissolved by the soul extinguishing bullet before he could scream.

With a successful blow, a smile appeared on Nuan Nuan's face.

Nuan Nuan said softly: "Xiaohu, Dr. Ou must be inside, now that we have found their location, I have to send the news back." ”

If there were only evil spirits inside, Nuan Nuan would definitely rush in without any worries, but there was Dr. Ou inside, and she was afraid that Dr. Ou would be hurt, so it was better to ask her grandfather.

Then Nuan Nuan took out her mobile phone, called her grandfather, and told her grandfather the news of the discovery of the evil spirit.

After Lin Guoguo received the call, he asked Nuan Nuan not to act rashly, and the next matter was handed over to the city defense army to deal with.

After Nuan Nuan hung up the phone, she sent the location to her grandfather, and then she stayed where she was with Brother Xiaohu, waiting for the arrival of the big army.

Nuan Nuan took out the drone from her backpack and pressed the switch on the drone.

Although Grandpa told her not to act rashly, she could do what she could, and first find out the situation inside.

A small sparrow flew up from the grass and headed for the abandoned factory.

In the blink of an eye, the sparrow flew into the factory.

Nuan Nuan used her mobile phone to connect to the drone, which was the sparrow just now.

Nuan Nuan controlled the sparrow's flight, bypassed the obstacles, and finally found the figure of the evil spirit.

The screen on the phone showed three men in black standing guard in front of an old and dilapidated house.

Could it be that Dr. Ou is locked up in that room? Nuan Nuan's heart became excited.

The sparrow flew over the head of the man in black and flew to the window of the room, and looked inside, but the window was one-way glass, and it was impossible to see inside.

Dr. Ou sat facing the window in the room, and the demon stream brought him food with two of his men.

After taking a bite of the fruit, Dr. Ou looked up just in time to see a small sparrow perched on the windowsill, looking in with its neck outstretched.

His mouth was wide open, because he could see that the sparrow was unique, with a bit of a long mouth, and he was sure that this was the drone.

He never expected that the drone would actually find here, and he was relieved in his heart, feeling that he was saved.

Then, the next thing to do is to stabilize these evil spirits.

"Hey, this sparrow really doesn't know whether to live or die, and dares to fly here." A man in black standing in front of the door said in surprise.

Then he stretched out his hand, emitted a black light, and rolled towards the sparrow in front of the window.

Nuan Nuan saw through the screen that the situation was wrong, she hurriedly controlled the sparrow, and flew in through the hole in the window.

When the man in black saw the sparrow flying into the room, he smiled lightly, feeling very funny, and said softly: "Hehe, this little sparrow is very sharp, I know that there is danger, then I will let you go." ”

The two men in black next to him nodded lightly in agreement, and then they didn't bother to pay attention to the sparrow that flew into the room.

"Tell me, how did you humans invent such a powerful weapon?" The Demon Stream asked.

Dr. Ou swallowed the fruit and said, "Because we humans are full of wisdom and can think of things that you can't think of. ”

"Nonsense, I'm not asking you this, I mean asking what materials your weapons are made of?" The demon stream glared fiercely at Dr. Ou.

Their every move, including their voices, was transmitted to Nuan Nuan by the sparrows that flew into the room.

Nuan Nuan looked at the picture transmitted back, and was very angry, these evil spirits captured Dr. Ou, and it was really for human technology.

The sparrow hovered above Dr. Ou's head and barked at Dr. Ou.

When the demon saw the sparrow coming to make trouble, he said to his subordinates, "Get rid of this pesky sparrow." ”

Without waiting for the Demon Stream's men to make a move, the sparrow flapped its wings and flew out.

"I am only responsible for leading the team to tackle key problems, handing over the theories researched to the engineers, and the engineers will lead the workers to produce, and I don't know what materials are used." Dr. Ou already thinks of himself as Lin Guoguo, and he speaks inconsequential words.

Because the room space is too small, Nuan Nuan is afraid that the evil spirits will catch the drone, otherwise these evil spirits will know that they are being monitored, and maybe they will move the location, so Nuan Nuan does not wait for the evil spirits to make a move, so she lets the drone fly out.

After the sparrow flew out, it flew around this abandoned factory, plus the evil spirits in the room, a total of nine evil spirits were found, and these evil spirits basically watched the entrance and exit of this factory, and they would be discovered if there was any movement outside.

The factory has four gates, each with a man in black who is in charge of guarding.

The evil spirit that was extinguished by the soul slayer just now was in charge of guarding the iron gate in front of Nuan Nuan.

Nuan Nuan breathed a sigh of relief in her heart, and the situation inside was basically clear.

Nuan Nuan was sure to kill these evil spirits who were in charge of vigilance silently, but the three evil spirits in the room were not easy to deal with, because they were right next to Dr. Ou.

It's not easy to rescue Dr. Ou.

Nuan Nuan took out her mobile phone and was about to call her grandfather to ask when the city defense army would arrive.

At this time, her mobile phone vibrate, and the call was from Runde, it turned out that after receiving Lin Guoguo's instructions, Runde personally led the troops to the vicinity, and called to ask Nuan Nuan if she had figured out the situation in the factory.

Nuan Nuan told Runde that the situation was clear, and she told Runde the number and specific location of the evil spirits inside.

Runde asked Nuan Nuan to wait to cooperate with him, which made Nuan Nuan very happy.

After a while, the city guards dressed in green clothes came and quietly surrounded the factory, and several evil spirits in charge of guarding were killed by the city guards before they could raise the alarm.

Runde's phone also called, asking Nuan Nuan to act first, because if the city defense army entered, it would scare the evil spirits inside, and they were afraid that the evil spirits would hurt Dr. Ou.

Runde asked Nuan Nuan to act at the opportunity, and if he couldn't do anything, he would come out immediately, and he would go in to save people while trying to ensure Dr. Ou's safety.

After hanging up the phone, Nuan Nuan and Brother Xiaohu hid the spirit killer gun in their pockets, and then put the evil spirit detector in their bags, after doing this, she carried her backpack and pulled Brother Xiaohu to pretend to come over to play, and walked towards the factory, and in the grass behind her, there were ambushes of the city guards.
